PESHAWAR, Pakistan — A suicide attack on a historic Christian church in northwestern Pakistan killed at least 75 people on Sunday in one of the deadliest attacks on the Christian minority in Pakistan in years.

The attack occurred as worshipers left the All Saints Church in the old quarter of the regional capital, Peshawar, after a service on Sunday morning. Up to 600 worshipers had attended the service and were leaving to receive free food being distributed on the lawn outside when two explosions ripped through the crowd.

Dozens of people were killed and more than 100 wounded, said Akhtar Ali Shah, the home secretary of Khyber Pakhtunkhwa Province.
